Review on 📞 Bellsouth Caller ID with Call Waiting CI 43: Enhanced Features for Efficient Call Management by Kevin Folsom

If I could give this product zero stars, I would. I needed a standalone caller ID box that I could connect to a special analog desk phone I have at work that didn't have caller ID built in. I needed to see who was calling this particular analog desk phone before answering, so I needed a working caller ID unit to identify incoming callers. The phone line in question is included with the caller's name and phone company identification number. This type of standalone caller ID was very common and cheap to buy in the 1980s - late 90s/early 2000s when everyone had an analog landline, but became very rare when the vast majority of people switched to Cellular and landline phones with built-in digital phone conversion display and caller ID. I bought my last caller ID from Walgreens in the late 1990's for about $10. Those were the good old days. Anyway, after much research on the internet I bought this box with BellSouth Caller ID (CI-43). I understand that this is a "new old" device (meaning it was made over 20 years ago but never used and is still boxed like new) but it should still work as it should. I connected this device to 2 different analog phone lines which the telco included caller name and number id as features to test and it never worked. The BellSouth block never displayed the incoming caller's number and name, as it should on those phone lines. I know these phone lines had caller ID on because I was using a more modern cell phone with caller ID built in as a test device and it was displaying incoming caller ID information as it should. I should mention that AT&T is the telco for my work and home. AT&T in Illinois was formerly known as Ameritech/SBC. I can only surmise that there could be two reasons why this BellSouth caller id blocker didn't work. The first reason is that the device may have been defective in the first place, and the second reason is that the device may only work with the BellSouth phone system (a carrier in the southern United States). If you have AT&T as your phone service provider and need offline caller ID, definitely don't buy this device. Luckily after a couple of weeks I was able to return this item to Revain for a full refund. .
